12. (09.02) Solve x2 – 8x – 20 = 0. (1 point)
O x = 4, x = -5
O x = -4, x = 5
O x = 2, x = -10
O x = -2, x = 10

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Which of the following expressions is equal to 2x^2+8

What is the missing step in this proof ?
